After upgrading to the current 2.0 release via ‘autoupgrade’, Piwik appears to have broken Simple XML in various other PHP sites on my VPS.
SimpleXML objects will load and sites will function correctly until I access the Piwik control panel, at which point they will fail, the SimpleXML object returning boolean false for a loaded file.
During ‘autoupgrade’ the installer seemed to go to a blank page but the Piwik installation seemed to upgrade correctly.
Any ideas what may be happening?
